A law passed two years ago to ease prison overcrowding sends parole violators to county jails instead of state prison. But many violators serve little or no time because jails have become overwhelmed.

Democratic Sen. Ted Lieu of Torrance says the offenders are more likely to commit new crimes if their whereabouts are not being monitored. His SB57 would require six months in county jail for a first offense and up to three years in state prison for repeat offenders.
